8) A frame is 2 cm tall and 4 cm wide. If it is reduced to a width of 2 cm , then how tall will it be?

Find the midpoint of the line segment with the given endpoints. \( \begin{array}{ll}\text { 23) }(-7,10),(-10,-10) \\ \mathrm{mPX}=-7+-10^{2} & \text { 24) }(-1,-6) \cdot(6,-5)\end{array} \)

\begin{tabular}{l} Find the midpoint between the two points. (Show work) (Page 26, 35) (2pts) \\ \hline\( G(-42,-22) \) and \( H(-62,92) \) \\ \( \left(x_{m}, y_{m}\right)=( \)\end{tabular}

Determine o valor de \( m \) para que as retas \( r \) e \( s \) sejam concor- rentes e ache o ponto de interseção, sendo \( r: \frac{x-1}{3}=y+2=\frac{z}{-2} \quad \) s: \( \left\{\begin{array}{l}x=m-t \\ y=1+t \\ z=2 t, t \in R\end{array}\right. \)
